Black Cotton Soil, also known as Regur soil, is a type of soil rich in clay and is primarily found in regions of India. It is characterized by its dark color, which is due to the presence of organic matter and minerals. This soil is highly fertile and is particularly suitable for growing cotton, hence its name. The formation of Black Cotton Soil is linked to volcanic activity, which contributes to its unique properties. It has excellent moisture retention capabilities, making it ideal for agriculture in areas with variable rainfall. Farmers often cultivate crops like sorghum and soybean in this nutrient-rich soil.
